5 WARNINGS AND PRECAUTIONS Hemorrhage: Major hemorrhagic events can occur during treatment with OJEMDA. Withhold, resume at reduced dose, or permanently discontinue based on severity. ( 5.1 ) Skin Toxicity Including Photosensitivity : Advise patients to monitor for new or worsening skin reactions. Advise patients to limit direct ultraviolet exposure and use precautionary measures such as sunscreen, sunglasses and/or protective clothing during treatment with OJEMDA. Withhold, reduce the dose or permanently discontinue based on severity. ( 5.2 ) Hepatotoxicity: OJEMDA can cause hepatotoxicity. Monitor liver function tests prior to administration and during treatment. Withhold, reduce the dose or permanently discontinue based on severity. ( 5.3 ) Effect on Growth : Reductions in growth velocity have been reported. Routinely monitor growth in pediatric patients. ( 5.4 ) Embryo-Fetal Toxicity : Can cause fetal harm. Advise of the potential risk to a fetus and to use effective nonhormonal contraception. ( 5.5 , 8.1 , 8.3 ) NF1 Associated Tumors : Increased tumor growth may occur with OJEMDA. (5.6, 13.2) 5.1 Hemorrhage Hemorrhage, including major hemorrhage defined as symptomatic bleeding in a critical area or organ, can occur with OJEMDA. In the pooled safety population [see Adverse Reactions (6.1) ], hemorrhagic events occurred in 37% of patients, including epistaxis in 26% and intratumoral hemorrhage in 9%. Serious events of bleeding occurred in 5% of patients including Grade 5 tumor hemorrhage in 1 patient (0.6%). OJEMDA was permanently discontinued for hemorrhage in 2% of patients. Advise patients and caregivers of the risk of hemorrhage during treatment with OJEMDA. Monitor for signs and symptoms of hemorrhage and evaluate as clinically indicated . Withhold and resume at reduced dose upon improvement, or permanently discontinue based on severity [see Dosage and Administration (2.5) ]. 5.2 Skin Toxicity Including Photosensitivity OJEMDA can cause rash, including maculopapular rash and photosensitivity. In the pooled safety population [see Adverse Reactions (6.1) ], rash occurred in 67% of patients treated with OJEMDA, including Grade 3 rash in 12%. Rash resulted in dose interruption in 15% of patients and dose reduction in 7% of patients. OJEMDA was permanently discontinued due to rash in 1% of patients (n=2). In the pooled safety population, dermatitis acneiform occurred in 26% of patients treated with OJEMDA, including Grade 3 dermatitis acneiform in 0.6% of patients (n=1). Dose reduction was required in 2% of patients (n=3) due to dermatitis acneiform. Monitor for new or worsening skin reactions. Consider dermatologic consultation and initiate supportive care as clinically indicated. Withhold, reduce the dose, or permanently discontinue OJEMDA based on severity of adverse reaction [see Dosage and Administration (2.5) ]. Photosensitivity In the pooled safety population [see Adverse Reactions (6.1) ], photosensitivity occurred in 12% of patients treated with OJEMDA, including Grade 3 events in 0.6% of patients (n=1). Advise patients to use precautionary measures against ultraviolet exposure such as use of sunscreen, sunglasses, and/or protective clothing during treatment with OJEMDA. Withhold, reduce the dose, or permanently discontinue OJEMDA based on severity of adverse reaction [see Dosage and Administration (2.5) ]. 5.3 Hepatotoxicity OJEMDA can cause hepatotoxicity. In the pooled safety population [see Adverse Reactions (6.1) ] , increased alanine aminotransferase (ALT) occurred in 42% and increased aspartate aminotransferase (AST) occurred in 74%, including Grade 3 ALT in 4% and increased AST in 2% of patients treated with OJEMDA. The median time to onset of increased ALT or AST was 14 days (range: 3 to 280 days). Increased ALT or AST leading to dose interruption occurred in 5% of patients and dose reductions were required in 1.2% of patients. Increased bilirubin occurred in 23% of patients, including Grade 3 increased bilirubin in 0.6% of patients (n=1) treated with OJEMDA. Hyperbilirubinemia leading to dose discontinuation occurred in a single adult patient with an advanced non-CNS solid tumor. Monitor liver function tests, including ALT, AST and bilirubin, before initiation of OJEMDA, one month after initiation and then every three months thereafter and as clinically indicated. Withhold and resume at the same or reduced dose upon improvement, or permanently discontinue OJEMDA based on the severity [see Dosage and Administration (2.5) ]. 5.4 Effect on Growth OJEMDA can cause reductions in growth velocity. In FIREFLY-1 [see Adverse Reactions (6.1) ] , treatment-emergent adverse effects on growth were reported in 46% of 133 patients 18 years of age or younger; 35% were Grade 3 or higher. Reduction in growth velocity resulted in dose interruption in 5% of patients, dose reduction in 2.3% of patients, and permanent discontinuation in 3% of patients. The median change from baseline in height percentile was -14 (z-score change -0.6) for evaluable patients on study for 12 months (N=107) and -20 (z-score change -0.9) for evaluable patients on study for 18 months (N=95). Growth velocity improved after interruption of treatment with OJEMDA. Among 81 evaluable patients, the median annualized growth velocity ranged from 0.86 to 1.8 cm/year during the 2-year treatment period. Of those, 17 patients had height measurements recorded at least 90 days off-treatment and had a 4.2 cm/year median annualized growth velocity. Routinely monitor patient growth during treatment with OJEMDA [see Adverse Reactions (6) , Use in Specific Populations (8.4) ]. 5.5 Embryo-Fetal Toxicity Based on findings from animal studies and its mechanism of action, OJEMDA may cause fetal harm when administered to a pregnant woman. Tovorafenib was embryo lethal in rats at doses approximately 0.8-fold the human exposure at the recommended dose based on area under the curve (AUC). Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective nonhormonal contraception during treatment with OJEMDA and for 28 days after the last dose, since OJEMDA can render some hormonal contraceptives ineffective [see Drug Interactions (7.2) ] . Advise male patients with female partners of reproductive potential to use effective contraception during treatment with OJEMDA and for 2 weeks after the last dose [see Use in Specific Populations (8.1 , 8.3) ]. 5.6 NF1 Associated Tumors Based on nonclinical data in NF1 models without BRAF alterations, tovorafenib may promote tumor growth in patients with NF1 tumors [see Nonclinical Toxicology (13.2) ]. Confirm evidence of a BRAF alteration prior to initiation of treatment with OJEMDA .

The safety population described in WARNINGS AND PRECAUTIONS reflects exposure to OJEMDA taken orally once weekly at a dose based on body surface area [see Clinical Studies (14) ] in 140 patients with relapsed or refractory pediatric LGG or advanced solid tumors harboring a RAF alteration and a flat dose of 600 mg in 32 adult patients with advanced solid tumors until disease progression or intolerable toxicity. Among 172 patients treated with OJEMDA, 86% were exposed for 6 months or longer and 49% were exposed for 1 year or longer. Pediatric Low-grade Glioma The safety of OJEMDA was evaluated in 137 patients with relapsed or refractory pediatric LGG harboring a BRAF alteration in FIREFLY-1 (Arms 1 and 2) [see Clinical Studies (14) ]. Patients received OJEMDA at a dose based on body surface area [see Dosage and Administration (2.3 ] orally once weekly until disease progression or intolerable toxicity. The median age of patients was 9 years (range 1 to 24 years); 53% male; 58% White, 7% Asian, 2% Black or African American, 6% other races, 25% race was not reported; 2.9% were Hispanic or Latino; and 90% Karnofsky/Lansky performance status of 80 to 100. Serious adverse reactions occurred in 45% of patients who received OJEMDA. Serious adverse reactions in >2% of patients included viral infection (9%), pneumonia (4%), and sepsis (4%). A fatal adverse reaction of tumor hemorrhage occurred in 1 patient (1%). Permanent discontinuation of OJEMDA due to an adverse reaction occurred in 7% of patients. Adverse reactions which resulted in permanent discontinuation of OJEMDA in more than one patient were tumor hemorrhage and reduction in growth velocity. Dosage interruptions of OJEMDA due to an adverse reaction occurred in 57% of patients. Adverse reactions which required dose interruption in ≥5% of patients included rash, pyrexia, vomiting, and hemorrhage. Dosage reductions of OJEMDA due to an adverse reaction occurred in 24% of patients. Adverse reactions which required dose reduction in ≥2% of patients included rash, and fatigue. The most common adverse reactions (≥30%) were rash, hair color changes, fatigue, viral infection, vomiting, headache, hemorrhage, pyrexia, dry skin, constipation, nausea, dermatitis acneiform, and upper respiratory tract infection. The most common Grade 3 or 4 laboratory abnormalities (≥2%) were decreased phosphate, decreased hemoglobin, increased creatine phosphokinase, increased alanine aminotransferase, decreased albumin, decreased lymphocytes, decreased leukocytes, increased aspartate transferase, decreased potassium, and decreased sodium.

( 7.2 ). 7.1 Effects of Other Drugs on OJEMDA Table 8 describes drug interactions where coadministration with another drug affects OJEMDA. Table 8 Coadministration with Other Drugs that Affect the Use of OJEMDA Strong or Moderate CYP2C8 Inhibitors Prevention or Management Avoid coadministration of OJEMDA with a strong or moderate CYP2C8 inhibitor. Mechanism and Clinical Effect(s) Tovorafenib is a CYP2C8 substrate. Strong or moderate CYP2C8 inhibitors are predicted to increase tovorafenib exposure based on a mechanistic understanding of its elimination [see Clinical Pharmacology (12.3) ], which may increase the risk of adverse reactions with OJEMDA. Strong or Moderate CYP2C8 Inducers Prevention or Management Avoid coadministration of OJEMDA with a strong or moderate CYP2C8 inducer. Mechanism and Clinical Effect(s) Tovorafenib is a CYP2C8 substrate. Strong or moderate CYP2C8 inducers are predicted to decrease tovorafenib exposure based on a mechanistic understanding of its elimination [see Clinical Pharmacology (12.3) ], which may reduce the effectiveness of OJEMDA. 7.2 Effects of OJEMDA on Other Drugs Table 9 describes drug interactions where coadministration with OJEMDA affects another drug. Table 9 Coadministration with OJEMDA that Affects the Use of Other Drugs CYP3A Substrates Prevention or Management Hormonal Contraceptives : Avoid coadministration of hormonal contraceptives with OJEMDA. If coadministration is unavoidable, use an additional effective nonhormonal contraceptive method during coadministration and for 28 days after discontinuation of OJEMDA. Other CYP3A Substrates: Avoid coadministration of OJEMDA with certain CYP3A substrates where minimal concentration changes may lead to serious therapeutic failures. If coadministration is unavoidable, monitor patients for loss of efficacy unless otherwise recommended in the Prescribing Information for CYP3A substrates.

8 USE IN SPECIFIC POPULATIONS Lactation : Advise not to breastfeed. ( 8.2 ) Infertility : May impair fertility in males and females. ( 8.3 ) 8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1) ], OJEMDA can cause fetal harm when administered to a pregnant woman. There are no available data on the use of OJEMDA in pregnant women. Oral administration of tovorafenib to pregnant rats during the period of organogenesis resulted in embryo lethality at exposures 0.8 times the human exposure at the recommended dose based on AUC ( see Data ). Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In an embryo-fetal development study, once daily oral administration of tovorafenib to pregnant rats during the period of organogenesis from gestation days 7 through 17 at doses of 37.5, 75, and 150 mg/kg resulted in early resorptions and total litter loss at all doses. The dose of 37.5 mg/kg/day is approximately 0.8-fold the human exposure at the recommended dose based on AUC. 8.2 Lactation Risk Summary There are no data on the presence of tovorafenib or its metabolites in human milk, their effects on the breastfed child, or on milk production. Due to the potential for serious adverse reactions in breastfed children from OJEMDA, advise lactating women not to breastfeed during treatment with OJEMDA and for 2 weeks following the last dose. 8.3 Females and Males of Reproductive Potential OJEMDA can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1) ]. Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating OJEMDA [see Use in Specific Populations (8.1) ] . Contraception Females Advise females of reproductive potential to use effective nonhormonal contraception during treatment with OJEMDA and for 28 days after the last dose. OJEMDA can render hormonal contraceptives ineffective [see Drug Interactions (7.2) ]. Males Advise male patients with female partners of reproductive potential to use effective contraception during treatment with OJEMDA and for 2 weeks after the last dose. Infertility Based on findings in animals, OJEMDA may impact fertility in males and females of reproductive potential. The effects on male animal fertility were reversible. The effects on female animal fertility were not reversible [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use The safety and effectiveness of OJEMDA in pediatric patients 6 months of age and older with relapsed or refractory pediatric LGG harboring a BRAF fusion or rearrangement, or BRAF V600 mutation have been established based on data from a multicenter, open-label, single-arm clinical trial [see Clinical Studies (14) ] . The efficacy of OJEMDA was evaluated in 76 patients with relapsed or refractory pediatric LGG . The safety of OJEMDA was evaluated in 137 patients with relapsed or refractory pediatric LGG in FIREFLY-1 (Arms 1 and 2). Of these 137 patients, 2% (n=3) were 6 month to < 2 years of age, 67% (n=92) were 2 years to < 12 years of age, and 31% (n=42) were >12 years of age [see Adverse Reactions (6.1) ]. C max and AUC in pediatric patients aged 11 months to 17 years were within the range of values observed in adults given the same dose per body surface area. The safety and effectiveness of OJEMDA in patients younger than 6 months of age have not been established. Effect on Growth Patients with pediatric LGG treated with OJEMDA for up to 24 months showed reductions from baseline in Z-scores for height compared to age and sex-matched normative data. Among 35 patients who experienced reductions in growth velocity who had hand radiographs taken to assess bone age, there was no evidence of premature closure of the epiphyseal growth plates or advancement of bone age. Patients followed after interruption of treatment with OJEMDA showed recovery of growth and increase in Z-scores. Monitor growth routinely during treatment [see Warnings and Precautions (5.4) ]. 8.6 Hepatic Impairment No dose adjustment is recommended for patients with mild (bilirubin ≤ upper limit of normal (ULN) and aspartate aminotransferase (AST) > ULN or bilirubin > 1× to 1.5× ULN and any AST) hepatic impairment. OJEMDA has not been studied in patients with moderate (bilirubin > 1.5× to 3× ULN and any AST) to severe (bilirubin > 3× ULN and any AST) hepatic impairment [see Clinical Pharmacology (12.3) ]. 8.7 Renal Impairment No dose adjustment is recommended for patients with mild-to-moderate renal impairment (eGFR ≥ 30 mL/min/1.73 m 2 calculated by Schwartz equation or MDRD equation). OJEMDA has not been studied in patients with severe renal impairment (eGFR <30 mL/min/1.73 m 2 ) [see Clinical Pharmacology (12.3) ] .

Chemical Structure

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Tovorafenib is a Type II RAF kinase inhibitor of mutant BRAF V600E , wild-type BRAF , and wild-type CRAF kinases. Tovorafenib exhibited antitumor activity in cultured cells and xenograft tumor models harboring BRAF V600E and V600D mutations, and in a xenograft model harboring a BRAF fusion. 12.2 Pharmacodynamics Exposure Response Relationships Tovorafenib exposure is associated with reduction in height-for-age z-scores in pediatric patients. Reduced height-for-age risk persists during treatment with tovorafenib. Higher tovorafenib exposure is associated with increased risk of skin rash, elevated liver enzymes (AST and ALT), and elevated creatine phosphokinase. The exposure-response relationship for overall response rate based on RAPNO-LGG (Response Assessment in Pediatric Neuro-Oncology), and RANO-LGG (Response Assessment in Neuro-Oncology) were not clinically significant over the dosage range of 290 to 476 mg/m 2 (0.76-1.25 times the approved recommended dosage) [see Dosage and Administration (2.3) and Clinical Studies (14) ] . Cardiac Electrophysiology At the recommended OJEMDA dosage of 380 mg/m 2 orally once weekly (not to exceed 600 mg), a mean increase in the QT interval >20 milliseconds was not observed. 12.3 Pharmacokinetics Tovorafenib pharmacokinetic parameters are presented as mean (CV%) unless otherwise indicated. Tovorafenib steady state maximum concentration (C max ) is 6.9 µg/mL (23%) and the area under the concentration-time curve (AUC) is 508 µg*h/mL (31%). Time to reach steady state of tovorafenib is 12 days (33%). Tovorafenib exposure increases in a dose-proportional manner. No clinically significant tovorafenib accumulation occurs. Absorption Tovorafenib median (minimum, maximum) time to achieve peak plasma concentration (T max ) is 3 hours (1.5, 4 hours), following a single dose with tablets or oral suspension. Effect of Food No clinically significant differences in tovorafenib C max and AUC were observed following administration of tablets with a high-fat meal (approximately 859 total calories, 54% fat) compared to fasted conditions, but the T max was delayed to 6.5 hours. Distribution Tovorafenib apparent volume of distribution is 60 L/m 2 (23%). Tovorafenib is 97.5% bound to human plasma proteins in vitro. Elimination Tovorafenib terminal half-life is approximately 56 hours (33%) and the apparent clearance is 0.7 L/h/m 2 (31%). Metabolism Tovorafenib is primarily metabolized by aldehyde oxidase and CYP2C8 in vitro. CYP3A, CYP2C9, and CYP2C19 metabolize tovorafenib to a minor extent. Excretion Following a single oral dose of radiolabeled tovorafenib, 65% of the total radiolabeled dose was recovered in the feces (8.6% unchanged) and 27% of the dose was recovered in the urine (0.2% unchanged). Specific Populations No clinically significant differences of tovorafenib were observed based on age (range: 1 to 94 years), sex, race (White, Black, Asian), mild hepatic impairment [bilirubin ≤ upper limit of normal (ULN) and AST > ULN or bilirubin > 1 to 1.5× ULN and any AST], and mild-to-moderate renal impairment (eGFR) ≥ 30 mL/min/1.73 m 2 calculated by Schwartz equation or MDRD equation. Drug Interaction Studies Clinical Studies and Model-Informed Approaches CYP3A Substrates: Midazolam (CYP3A4 substrate) steady-state C max and AUC are predicted to decrease by at least 20% following coadministration with tovorafenib. In Vitro Studies CYP450 Enzymes : Tovorafenib inhibits CYP2C8, CYP2C9, CYP2C19 and CYP3A, but does not inhibit CYP1A2, CYP2B6, and CYP2D6 at clinically relevant concentrations. Tovorafenib induces CYP3A, CYP2C8, CYP1A2, CYP2B6, CYP2C9 and CYP2C19 at clinically relevant concentrations. Transporter Systems: Tovorafenib is not a substrate of BCRP, P-glycoprotein (P-gp), OATP1B1 and OATP1B3. Tovorafenib has not been evaluated as a substrate of OAT1, OAT3, MATE1, MATE2-K and OCT2. Tovorafenib inhibits BCRP at clinically relevant concentrations.

13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Tovorafenib was not carcinogenic in the 6-month study in transgenic rasH2 mice that received oral doses up to 100 mg/kg/day. Tovorafenib was not mutagenic in the in vitro bacterial reverse mutation (Ames) assay. Tovorafenib was not genotoxic in cultured human lymphocytes without metabolic activation. Tovorafenib induced chromosomal aberrations in cultured human lymphocytes with metabolic activation at a single concentration in vitro. Tovorafenib was not genotoxic in an in vivo rat bone marrow micronucleus assay. In a fertility and early embryonic development study in rats, animals were administered tovorafenib doses of 37.5, 75, or 150 mg/kg/day orally. Female animals, paired with untreated males, were dosed for 14 days prior to pairing, during the mating period, and up to Gestation Day 6. Tovorafenib decreased the number of pregnancies, corpora lutea, and live embryos, as well as increased post-implantation losses at all doses. The dose of 37.5 mg/kg/day is approximately 0.8-fold the human exposure at the recommended dose based on AUC. In repeat- dose toxicology studies in rats of up to 3 months duration, tovorafenib-related findings in female rats included reversible increased thickness of the vaginal mucosa, increased size and/or numbers of corpora hemorrhagicum and hemorrhage, and non-reversible cystic follicles, decreased corpora lutea, and interstitial cell hyperplasia were observed in ovaries at doses ≥ 50 mg/kg once every other day (approximately 0.4-fold the human exposure at the recommended dose based on AUC). In male rats, tovorafenib reduced weights of epididymis and testes, which correlated with reversible tubular degeneration/atrophy of the testes and reduced epididymal sperm at doses ≥ 50 mg/kg once every other day (approximately 0.3-fold the human exposure at the recommended dose based on AUC). 13.2 Animal Toxicology and/or Pharmacology In vitro, tovorafenib increased phosphorylation of ERK at clinically relevant concentrations in cells with neurofibromatosis Type 1-loss of function (NF1-LOF) suggesting activation, rather than inhibition, of the MAP kinase pathway. In an NF1 genetically engineered mouse model of plexiform neurofibroma without BRAF alteration, tovorafenib did not have antitumor activity, and while not statistically significant, an increase in tumor volume was noted in 2/12 mice (approximately 17%).

14 CLINICAL STUDIES The efficacy of OJEMDA was evaluated in a multicenter, open-label, single-arm clinical trial (FIREFLY-1; NCT04775485). Eligible patients (N=76) were required to have a relapsed or refractory pediatric low-grade glioma (LGG) harboring an activating BRAF alteration based on local laboratory testing. Patients were also required to have at least one measurable lesion as defined by RANO 2010 criteria. All patients had received at least one line of prior systemic therapy and had documented evidence of radiographic progression. Patients with tumors harboring additional activating molecular alteration(s) (e.g., IDH1/2 mutations, FGFR mutations, etc.) or patients with known or suspected diagnosis of neurofibromatosis type 1 (NF1) were excluded. Patients received OJEMDA approximately 420 mg/m 2 orally once weekly (range: 290 to 476 mg/m 2 , 0.76-1.25 times the approved recommended dosage) according to body surface area with a maximum dose of 600 mg until disease progression or unacceptable toxicity. Although the OJEMDA dosages administered in FIREFLY-1 were between 290 mg/m 2 to 476 mg/m 2 , the recommended OJEMDA dosage is 380 mg/m 2 orally once weekly because this dosage was determined to be safe and effective for the treatment of patients 6 months of age and older with relapsed or refractory pediatric LGG harboring a BRAF fusion or rearrangement, or BRAF V600 mutation [see Dosage and Administration (2.3) ]. Tumor assessments were performed every 12 weeks. The major efficacy outcome measure was overall response rate (ORR), defined as the proportion of patients with complete response (CR), partial response (PR), or minor response (MR) by blinded independent central review based on RAPNO-LGG (Response Assessment in Pediatric Neuro-Oncology) criteria. Additional efficacy outcome measures were duration of response, time to response, and ORR by independent review based on RANO-LGG (2011) criteria. The efficacy population included 76 patients who had measurable disease at baseline and who received OJEMDA. The median age was 8.5 years (range 2 to 21 years); 53% were male; 61% White, 7% Asian, 2.6% Black or African American, 3.9% multiple races, 8% other race, 18% where race was not reported; 3.9% were Hispanic or Latino, and 93% had Karnofsky/Lansky performance status of 80 to 100. Patients received a median of 3 prior systemic regimens (range: 1 to 9). Forty-five patients (59%) received prior treatment with a MAP kinase pathway inhibitor. The most common tumor locations were the optic pathway (51%), deep midline structures (12%), brain stem (8%), cerebellum (7%), and cerebral hemisphere (5%). Fifty-six patients (74%) had a KIAA1549:BRAF fusion, twelve patients (16%) had a V600E mutation, and eight patients (11%) had a BRAF alteration classified as "other" including BRAF duplication or BRAF rearrangement. Efficacy results are shown in Table 10.

In exploratory analyses of BRAF alteration status, the ORR was 53% among patients with BRAF fusion or rearrangement (n=64), and 50% among patients with BRAF V600E mutation (n=12), respectively. In exploratory analyses of prior therapies, the ORR was 51% among patients who had received prior MAPK-targeted therapy (n=45), and 55% among patients who had not received prior MAPK-targeted therapy (n=31). Based on RANO-LGG (2011) criteria (n=76), the ORR was 54% [95% CI: (42, 65)], including 23 patients with PR and 18 patients with MR.

Wash and dry your hands before preparing, measuring, and taking or giving a dose of OJEMDA for oral suspension. Step 2. Place your supplies on a clean, flat work surface. Step 3. Fill a cup half-way with room temperature water. Do not use cold water. Step 4. Remove air from the oral dosing syringe. Pull the plunger up into the oral dosing syringe as far as it will go, and then push the plunger back down into the oral dosing syringe as far as it will go. This will help to remove all the air inside. Step 5. Place the oral dosing syringe tip in the water. Pull up on the plunger to draw water into the oral dosing syringe to the 14 mL mark. Note: Add exactly 14 ml of water to the bottle with powder. Step 6. Remove the oral dosing syringe from the cup. Turn the oral dosing syringe tip upward and check for air bubbles. If large air bubbles appear in the oral dosing syringe, push the water back into the cup and then pull up on the plunger again to draw up the water to the 14 mL mark.

Do not shake the bottle for more than 2 minutes total time. Check the bottle to make sure all of the powder is no longer visible. If you still see powder in the bottle, contact your healthcare provider or pharmacist and ask for a new bottle. Step 10. Turn the bottle upside down again and swirl for 30 seconds. Place the bottle on a flat, clean, work surface. Remove the cap and check that no solids are stuck in the bottle neck. If you see solids in the bottle neck, recap the bottle, turn the bottle upside down, and swirl for an additional 15 seconds. Allow the bottle to sit for 60 seconds to allow most of the foam to settle. Note: Foaming in the bottle will reduce the amount of OJEMDA for oral suspension. Step 11. Open the bottle by firmly pressing down on the cap and turning it to the left (counterclockwise). Do not throw away the cap. Firmly insert the bottle adaptor into the bottle by pushing it tightly into the top of the bottle. The top edge of the bottle adaptor should be even with the bottle top. Do not remove the bottle adaptor after it is inserted into the bottle. Step 12. Check your or your child's dose in milliliters (mL) as prescribed by your healthcare provider. Pick up the oral dosing syringe again. Each mark on the oral dosing syringe is equal to 1 mL. Draw air into the oral dosing syringe by pulling the plunger out to your prescribed dose. For example, if your prescribed dose is 12 mL, you would draw the oral dosing syringe by pulling the plunger out to the 12 mL mark. Step 13. Insert the tip of the oral dosing syringe into the bottle adaptor. The tip of the oral dosing syringe should fit snugly into the hole of the bottle adaptor. Keep the oral dosing syringe attached to the bottle. With the oral dosing syringe in place and holding the bottle where the oral dosing syringe tip inserts into bottle adaptor, swirl the oral suspension for 30 seconds. Step 14. Inject the air from the oral dosing syringe into the bottle. Hold the oral dosing syringe in place and turn the bottle upside down. To measure the prescribed dose, keep the tip of the oral dosing syringe facing up and pull down on the plunger until the top of the plunger lines up with the prescribed dose in mLs. Step 15. While the syringe is still in the bottle, remove any air bubbles in the oral dosing syringe by gently pushing the OJEMDA oral suspension back into the bottle and then pulling down on the plunger again to draw up your prescribed dose. Repeat Step 15 until you see that few or no air bubbles remain or if you draw up the wrong dose in the oral dosing syringe. Note: Only use up to 12 mL of OJEMDA oral suspension from each prepared bottle. If the prescribed dose is more than 12 mL (300 mg), split the dose as equally as possible between each prepared bottle. For example, if your dose is 13 mL, draw 6 mL from the first prepared bottle, and 7 mL from the second prepared bottle. Step 16: Leave the tip of the oral dosing syringe in the bottle adaptor and carefully turn the bottle upright. Put the bottle onto your flat work surface again. Slowly remove the oral dosing syringe tip from the bottle adaptor by gently pulling straight up. Do not hold the oral dosing syringe by the plunger because the plunger may come out. Step 17: Check again to be sure the top of the black stopper on the barrel of the oral dosing syringe is at your prescribed mL dose mark. If you do not have the correct prescribed mL dose, repeat Steps 15 to 17. If you are taking or giving a dose of OJEMDA for oral suspension by mouth, continue to Step 18 . If you are taking or giving a dose of OJEMDA for oral suspension through a feeding tube, go to Section B . OJEMDA for oral suspension must be given within 15 minutes after prepared for use. Step 18. You or your child should sit upright to take or give a dose of OJEMDA oral suspension. Place the tip of the oral dosing syringe towards the inside of the cheek in your or your child's mouth. Slowly push the medicine into the mouth by pressing down on the plunger. Do not forcefully push the plunger. This may cause choking. Allow the child to swallow while giving OJEMDA. You or your child may drink liquids right away after swallowing the OJEMDA for oral suspension. Be sure to take or give the entire dose of OJEMDA for oral suspension. If 2 bottles of OJEMDA for oral suspension are required to take or give your prescribed dose, repeat Section A, Steps 1 to 18 for the second bottle. Throw away the prepared OJEMDA for oral suspension if it is not taken or given within 15 minutes. Step 19: See Section C for instructions on " How to throw away used bottles, expired or unused OJEMDA for oral suspension, and oral dosing syringes" Section B: Taking or giving a dose of OJEMDA or oral suspension through a feeding tube Before giving a dose of OJEMDA for oral suspension through a feeding tube, read the following information and talk to your or your child's healthcare provider before continuing to STEP 20 : OJEMDA for oral suspension may be given through a feeding tube, as directed by your healthcare provider. Only use a feeding tube with a minimum size of 12 French. Always use the 20 mL oral dosing syringe (included in the box) to prepare each dose of OJEMDA for oral suspension in the bottle. Always use a 20 mL ENFIT syringe and an ENFIT adaptor (neither included in the box) to measure and give each dose of OJEMDA for oral suspension through the feeding tube. Step 20. Flush the feeding tube according to the manufacturer's instructions before giving a dose of OJEMDA for oral suspension. Step 21: Follow Steps 1 to 11 in Section A to prepare the OJEMDA oral suspension using the 20 mL oral dosing syringe. Follow Steps 12 to 17 in Section A to draw up your or your child's dose of OJEMDA for oral suspension using the ENFIT syringe and ENFIT adaptor. Step 22: Connect the 20 mL ENFIT syringe containing OJEMDA for oral suspension to the feeding tube. Step 23: Apply steady pressure to the plunger to give the entire dose of OJEMDA for oral suspension through the feeding tube. Step 24: Flush the feeding tube after giving each dose of OJEMDA for oral suspension according to the manufacturer's instructions. If 2 bottles are required, repeat Step 21 and give the remainder of the dose right away. Step 25: Go to Section C for instructions on " How to throw away used bottles, expired or unused OJEMDA for oral suspension, and oral dosing syringes" Section C: How to throw away used bottles, expired or unused OJEMDA for oral suspension, and oral dosing syringes Throw away your used bottle(s), expired or unused OJEMDA for oral suspension, and oral dosing syringe(s) in your household trash. Do not re-use the oral dosing syringe(s). How should I store OJEMDA? Store the glass bottle containing OJEMDA for oral suspension at room temperature between 68˚F to 77˚F (20˚C to 25˚C).
